Application February 14, 1946, Serial No. 647,492

1 This invention relates to improvements in display gures or dummies,fasthey are mainlyused for advertising purposes or'the like and more particularly to a new and useful limb connecting and adjusting device for such figures.

It is the principal object of our invention-to provide such a device which will permit a ready and convenient regulation and adjustment of the limbs, especially the arms in their respective desired relative. positions to the body, at any desired angle thereto.

Another object of the invention is to provide such a device equipped with an adjusting turning point allowing a readyy turning of the arms into any desired or required position relatively to the iigures body and to lock the same in this position.

A further object of our invention is to provide such a device including a closing housing to be embedded into the material of the ligure or its limbs provided with suitable outer threaded flanges and holes for the admittance of plastic material or the like. j

A still further object of our invention is to provide such adevice which is comparatively simple and inexpensiveyet durable and eicientin use and operation. L

These and other objects and advantages of our invention will become more fully known as the description thereof" proceeds and will then be more specifically defined in the accompanying claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 illustrates fragmentarily the application of a connection between the arm and body of a dummy figure constructed according to our invention.

Fig. 2 is a diametral sectional view ofthe joint.

Fig. 3 is a inner face view of one of the adjustable plate members, partly in section.

Figure 4 is similar, but with the components in position ready to be disconnected.

Figure 5 is a view similar to Figure 4 but with both components revolved 90 degrees on the axis of bolt I2.

Referring now in detail to the drawings, a display manikin body IU is provided with a female component IUC of the limb connection, while an arm IUD adapted for detachable connection to the body IU is provided with the male component IUE of the limb connection. The female component IUC comprises the plate B formed with the eccentric circular hole II communicating with the centrally located rectangular hole IIA to formv the hole IIB, in which the portion II is 7 claims. (o1. 287-101) of greater Vdiameter'than the width of the-rectangular portion IIA'. Y The male component IUE comprises the 'plate A through which passes the centrallyvloc'ated-bolt I2 on which is rotatably mounted the concentric stud I3 of generally cylindrical shape. l' Thestd I3 comprises the cylindrical head portion-"IBA and is relieved as atA I4 so as to comprise the' neck portion IAA, the lattervcomprisingtwo parallel sides which fit snugly and non-rotatably into the rectangular portion IIA ofthe hole IIB in plate B, the head I3A being proportioned -to pass through the circular'hole Il in plate B. il

A nut I5 and washer IEA are preferably firmly fastened to the rear surface of plate-A. 1

A cylindrical housing I6,'closed atv-its outer end IEA, is rmly yfastened to the rear surface of plate A concentricallytherewith and sur-"- rounding nut I'5 and bolt I2. A cylindrical housing I'I, closed at its outer end I'IA, is firmly fastened to the rearsurface of plate-B 4in concentric relation. r A'ridge I8v extends outwardly from ther cylindrical surface of housing I'I, extending sinuously therearound -f and describing preferably two or more Yconvolutions toward and away from plate B. as clearly shown by a comparison of Figures 4 and 5. A similar ridge I9 is formed in the cylin-I drical wall of housingIS. `It is Ythus evidentthat when the housings I6, I'I are embedded inwet plastic material and placed in their respective parts of the display figure, upon the plastic material hardening the components are fixed against any motion relative to the parts of the figure in which they are embedded. f

The bolt I2 being threaded, is threadedly engageable with nut I5 and can be tightened therein or loosened at will, thereby rendering stud I3 xed relative to plate A or rotatable relative thereto. The engagement between stud I3 and plate A being frictional, it is also possible to tighten bolt I2 just enough to permit rotation between stud I3 and plate A upon the application of a considerable predetermined force as will be explained hereafter.

Withk the bolt I2 screwed very tight into nut I 5, the stud I3 is for all practical purposes firmly fixed against rotation, relative to plate A. It thus has a definite angular relation to the manikin body IU or other limb in which plate A is fixed. By introducing head I 3A of stud I3 into the hole IIB, as best shown in Figure 4, that is, with the head I3A concentric with the hole II, head I3A passes through hole II and the arm IUD carrying the plate A and the stud I3 will A 3 drop by forc of lgravity to the position shown in Figures 2 and 3. The arm or other limb 10D is now in a xed angular relation to the display Figure l0 and cannot be moved out of said angular relation without either detachment of the arm from the figure or adjustment of the male component 10E.

If a different fixed angular relation of limb to iigure is desired, the limb is first removed in obvious manner and bolt l2 unscrewed and the stud ,f

I3 rotated relative to plate A the desired amount, and the bolt l2 again tightened down very tight. When the arm IUD is again attached it will have a different iixed angular relation to the display Figure 10. It is also possible to tighten bolt l2 to such a degree that the arm IUD or other limb will maintain any position to which it is set, and yet may be moved angularly relative to body lll. Such movement of the arm IDD carries with it plate A, while stud i3 is nonrotatably held in pla-te B. The arm IDD willthen maintain the new position to which it has-been set.

case it is not desired to provide adjustability of angular position of the limb relative to the body the bolt l2 may be screwed. into the nut i5 to the maximum lextent providing maximum frictional engagement between stud i3 and plate A, and the bolt II2 may then be iixed relative to nut i5 by any well known method.

It will thus be seen, that there is provided a device in which the several objects of this invention are achieved, and which is Well adapted to meet the conditions of practical use. As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying .drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described vour invention, what we claim is:

vl. In -a limb connection for display iigures, the combination with a plate, vsaid plate comprising means adapted to interengage with means of a cooperating plate to detachably connect said plates together, of a substantially cylindrical housing connected to said plate, said housing comprising a ridge portion extending sinuously therearoimd.

2. In a limb connection according to claim i, said ridge portion describing a plurality of con-f volutions toward and away from said plate.

3. In a limb connection for display figures, the combination with a plate formed with a hole therein, said hole comprising a lower substantially rectangular portion and an upper portion of greater width than said rectangular portion, of a plate Vcomprising means for detach-ably engaging said hole in said rst mentioned plate so as to lock said plates together, said means comprising a stud, said stud comprising a portion cornprising parallel sides so as to be nonrotatably engageable with the rectangular portion of said hole, said stud further comprising a head portion passable through the Wider portion of said hole, and means connecting said stud to said second plate, said plates further comprising means for attachment to parts of display gures.

4. In a limb connection according to claim 3, said means connecting said `stud to said second plate comprising a bolt passing through both and a nut engaging said bolt.

Y 5. In a limb connection according to claim 4, said stud being freely rotatable relative to said second plate and xable against rotation relative thereto by tightening of said nut and bolt.

16. In a limb connection according to claim 5, said -nut being firmly ixed to said plate on the side thereof opposite to said stud.

'7. In a limb connection for display iigures, the combi-nation of a plate and a vsubstantially cylindrical housing connected thereto, said housing comprising a ridge portion vextending sinuously therearound.
